My target system use two banks of SDRAM memory and external memory for SDRAM addresses are:
Bank0 0x00400000-0x01FFFFFF - width less 28 bit
Bank1 0x04000000-0x05FFFFFF - width less 28 bit
I want use scatter DMA.
Can I use scatter DMA as:
EIEP register is an increment count and data in tap list is absolute addresses.
EIEP + data in tap list is absolute addresses = 28bit address
Am I right?
